THRASHlNG-MACHINE STRAW-CARRIER.

SPECIFICATION forming part of Letters Patent No. 305,979, datedseptember 30, 1884,

Application filed January 30, 1883. (No model.)

To all whom it may concern.-

Be it known that I, ISAAC STARR, a citizen of the United States,residing at Richland, county of Kalamazoo, State of Michigan, haveinvented a new and useful Thrashing-Maehine Straw-Oarrier, of which thefollowing is a specification. My invention relates to that class ofstraw carriers which are so constructed and pivoted that their elevatedend, next to the straw-stack, may be located in different positionsvertically and laterally by turning in their pivot-connections at thelower end, in order thatthe straw maybe delivered at different locationson the stack.

My invention has for its object certain improvements in construction andarrangement, whereby the device is simplified and cheap ened, itsutility increased, and the carrier connected with the thrasher in amanner to be transported with it and form a connected part thereof.

In the drawings forming a part of this specification, Figure 1 is a sideelevation of the straw-carrier connected with the rear end of athrashing'inaehine; Fig. 2, the same, showing a curtain connectedtherewith; Fig. 3, a top view of a portion of Fig. 1,.hereinafterexplained, Fig. 4, a top view of the straw-carrier support; and Fig. 5,a view of the lower end of the pivoted straw-carrier, looking from thethrasher, with a portion in section on a line with. the vertical centerof pintle a.

B illustrates the rear end of a thrashing-machine.

A is a short straw and chail' carrier, common in such machines, exceptin those not using the pivoted carrier R. It extends to a greaterheight. Supporting-beams D D are secured to the frame of the machine 13,and extend rearwardly at converging angles. \Vhere the ends meet theyare provided with a circular plate, D, having a pivot-hole, e, extendingdown through the beams. Beam a, which supports the lower end of carrierR, is pivoted on plate D by means of a hollow pintle, a. The upper endof this pintle terminates in brackets b b, which form bearings for shaft25 in the center. The ends of this shaft have rim 1*.

hearings in brackets (l d, which project upward from beam a.

n n are the lower belt-wheels of the carrier, secured to shaft 1. Twosets of belts, a u, with slats y are used in the carrier, in order tolocate the propelling-gear at the center of shaft t and over the pointof pivoting.

a shows one of the upper belt-wheels. Gear S terminates the upper end ofthe vertical shaft .2, and meshes with the gear S of shait t. Abelt-pulley, U, is secured to the lower end of shaft 2, with which abelt may be connected from the power mechanism. Shaft 2 is located inthe hollow pintle a and revolves therein. The lower end of the pivotedcarrier It is pivoted on shaft f in a manner that the elevated end maybe raised and lowered, as in other carriers. Plate D has a circularelevated rim, 7), upon which the carrier-beam a rests and turns. Thisforms a balancing support to the lower end of the pivoted carrier at alllocations, similar to the fifth-wheel of an axle in a vehicle.

In order that carrier It shall not turn too easily on its pivot a, Iprovide friction-bars z i, secured to the under side of beam a.. One endof said bars engages the under surface of The degree of their frictionalengage ment is controlled by tightening or loosening the bolts whichsecure said bars to beam a.

T is a carrier constituting a rear extension to the pivoted carrier R,located between the upper end of carrier A and the lower end ofcarrierR, said intermediate carrier being extended well to the rear of thepoint of pivot ing, as in Fig. 1.

The carrier T consists of an endless web passing around shafts whichhave bearings in the ends of bars 1' m. The web extends from one side ofthe carrier R to the other. Bars r m are secured to the brackets at eachend of beam a, as shown at the right of Fig. 5.

c is a belt located around pulleys f f, inr parting motion from shaft tto the intermediate carrier, T.

Fig. 3 illustrates the use of carrier T. \Vhen the carrier It is carriedto the right or left, as indicated by the dotted lines, were it not forthe carrier T, or that portion-of it which ex tends in the rear of thepivot a, a space would be left at the rear corners, through which strawand chaff would fall after leaving the carrier A.

F is a rope for raising the carrier R. It is similar to formerarrangements, except that after leaving the windlass h it passes under apulley, b, on the rear corner of the machine 13; then around a pulley,a, secured to the under side of the carrier It; thence across the samearound a like pulley, c, on the other side, and under a like pulley, b,on the other side of the machine, and then it is connected to the otherend of the windlass h. By this means, when the carrier R is movedlaterally, the rope F moves around the pulleys a, necessitating lesslateral sway of the rope, and pulleys I) 7) cause the rope to alwayswind squarely on the windlass.

C is a curtain located on each side of the machine in the position shownin Fig. 2. This curtain is supported by a frame composed of rods 0 c andropes c a, secured together at the points of connection shown. It isconnected to the machine by spring 0, and to the pivoted carrier by theropes c c, passing through holes 1 2, crossing on the under side of saidcarrier, passing through like holes on the other side, and connectingwith a like curtain on the other side of the machine, hen the carrier isadjusted laterally, it slips on the ropes, thus admitting of a freemovement without unduly swaying the curtain. \Vhen an unusual sidemovement is made, or when said carrier is raised or lowered at itselevated end, springo yields under the strain.

Having thus described my invention, what I claim is- 1. The combination,with a thrashing-machine, of a short carrier, upon which the straw andchaff first fall, a pivoted carrier adapted for lateral adjustment, andan intermediate carrier constituting an extension to the pivoted carrierin the rear of its pivot, for the object specified, all substantially asset forth.

2. The supporting-beams and balancing plate having the circular rim, incombination with a pivoted straw-carrier having the shaftsupportingbeam, and the brake-bars engaging the under side of said rim,substantially as described.

3. The combination, with a thrashing-machine provided with the windlassand corner pulleys, of a pivoted straw-carrier having the pulleysmounted on the under side thereof, and a rope connecting with thepulleys and Windlass, substantially as set forth.

4:. The combination, with a thrashinganachine and a straw-carrierpivoted to be adjusted vertically and laterally, of a curtain and asupporting-frame therefor, composed of the ropes and rods, allsubstantially as specified and shown.

In testimony of the foregoing I have hereunto subscribed my name in thepresence of two witnesses.

ISAAC START.
